Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an adjustable-height LED lighting lamp. Background Technology

[0002] LED lighting is a type of lighting device that uses LED technology as its light source. Compared to traditional lighting fixtures, LED lighting has significant advantages, including high energy efficiency and long lifespan. LED lights emit light by exciting electrons in semiconductor materials with an electric current, thus consuming far less energy than traditional incandescent and fluorescent lamps. Furthermore, LED lighting can achieve various color temperatures to meet the lighting needs of different environments and occasions, and is widely used in homes, offices, commercial spaces, and outdoor lighting.

[0003] Utility model patent CN220103035U discloses an adjustable LED lighting lamp, including a base with a support column mounted on it. A support plate is slidably fitted inside the support column, and a first driving mechanism is installed inside the support column to drive the support plate to slide. A sliding plate is slidably fitted above the support plate. This utility model allows for quick adjustment of the distance between the sliding plate and the support plate by activating the second driving mechanism. The sliding plate drives a connecting plate to rotate an electric push rod, facilitating adjustment of the lighting angle. After adjusting the lighting angle and direction, the electric push rod simultaneously drives the lighting lamp to slide horizontally, facilitating adjustment of the lighting position. The lighting lamp is adjusted to its original position, and the first driving mechanism allows for quick adjustment of the support plate's height, thereby adjusting the lighting height to its original height or illumination distance, ensuring sufficient brightness.

[0004] In existing technologies, adjusting the height of the support plate using a first drive mechanism to adjust the height of the lighting lamp is a common design. However, this first drive mechanism consists of a first servo motor, a first threaded rod, and a threaded cylinder, which presents some inconveniences during the adjustment process. For example, the first threaded rod is fully exposed after the threaded cylinder moves upward, making it susceptible to the influence of dust, impurities, and other contaminants in the environment. After prolonged use, the threaded connection between the first threaded rod and the threaded cylinder may become unsmooth or even jam, severely affecting the adjustment function of the lighting lamp. This design inconvenience not only affects the user experience but also negatively impacts the long-term stability of the lighting lamp. Therefore, to solve this problem, we propose an adjustable-height LED lighting lamp. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable-height LED lighting fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An adjustable height LED light includes a base with a fixed vertical plate on top. A top plate is located on the front side of the fixed vertical plate, and a height adjustment component is located on the top of the top plate. The height adjustment component controls the raising and lowering of the LED light. The height adjustment component includes a housing with a partition inside. A rotating shaft is rotatably connected to the front side of the partition, and a motor for driving the rotating shaft is located on the rear side of the partition. The motor's wires pass through the inner wall of the housing to the outside, and the connection between the wires and the housing is sealed. The motor's output shaft is equipped with an electromagnetic brake that automatically locks the motor shaft when power is off to prevent accidental slippage of the suspension rope. The outer wall of the rotating shaft is provided with two winding drums arranged symmetrically front and back. Each winding drum is wound with a suspension rope. The rotating shaft is used to drive the winding drums to rotate so as to realize the raising and lowering of the suspension ropes. The bottom ends of the two suspension ropes are connected to a mounting plate. The mounting plate is used to fix the LED light and transmit the lifting power. The bottom of the mounting plate is bolted to the LED light.

[0007] Preferably, the top plate has two clearance holes, through which the two hoisting ropes pass respectively. The top and bottom of the inner wall of the clearance holes are rounded, which reduces wear on the hoisting ropes.

[0008] Preferably, the top of the mounting plate is provided with two lifting rings arranged symmetrically front to back, and the two lifting rings are respectively connected to two lifting ropes. The lifting rings are used to connect the lifting ropes and the mounting plate.

[0009] Preferably, a limiting plate is provided on the rear side of the mounting plate, and a rectangular hole is provided at the bottom of the limiting plate near the rear side. The limiting plate restricts the horizontal displacement of the mounting plate to ensure vertical lifting.

[0010] Preferably, a rectangular upright is provided between the base and the top plate and near the rear side. The rectangular upright passes through a rectangular hole, and the inner wall of the rectangular hole does not contact the outer side of the rectangular upright. The rectangular upright serves as a vertical guide rail for the lifting and lowering of the mounting plate.

[0011] Preferably, each of the four inner walls of the rectangular hole has a groove, and each of the four grooves is rotatably connected to a roller. The four rollers roll on the four sides of the rectangular upright, reducing the frictional resistance between the rectangular upright and the limiting plate.

[0012] Preferably, the lower middle part of the front side of the fixed vertical plate is provided with a controller for controlling the forward and reverse rotation of the motor, and the controller realizes the control of the height of the LED light.

[0013] Preferably, mounting holes are provided on the top of the base and near the four corners, and the base is installed on the ground by anchor bolts to enhance stability.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This height-adjustable LED light achieves height adjustment by using a motor to drive a winding drum to raise and lower the suspension rope. It eliminates the need for exposed threaded rods and drums, avoiding thread jamming and improving the long-term reliability of the adjustment function.

[0015] 2. The height-adjustable LED light uses a rectangular pole that passes through a rectangular hole in a limiting plate. The rollers inside the groove roll on the side of the rectangular pole, which limits the horizontal displacement of the mounting plate and reduces frictional resistance during the lifting process, ensuring the stability of the LED light's vertical lifting.

[0016] 3. The height-adjustable LED light has rounded corners at the top and bottom of the inner wall of the clearance hole to prevent the hoisting rope from directly rubbing against the edge of the hole when it moves, thus extending the service life of the hoisting rope.

[0020] Please see Figures 1-4 This utility model provides a technical solution: An adjustable height LED light includes a base 100, a fixed vertical plate 200 on the top of the base 100, a top plate 300 on the front top of the fixed vertical plate 200, and a height adjustment component 400 on the top of the top plate 300. The height adjustment component 400 is used to control the lifting and lowering adjustment of the LED light 600. The height adjustment component 400 includes a housing 410, a partition 411 inside the housing 410, a rotating shaft 420 rotatably connected to the front side of the partition 411, and a motor 440 for driving the rotating shaft 420 to rotate on the rear side of the partition 411. The wires of the motor 440 pass through the inner wall of the housing 410 to the outside. The connection between the wires and the housing 410 is sealed. The output shaft of the motor 440 is equipped with an electromagnetic brake (not shown in the figure). The electromagnetic brake automatically locks the rotating shaft of the motor 440 when the power is off to prevent the suspension rope 450 from slipping accidentally. The outer wall of the rotating shaft 420 is provided with two winding drums 430 arranged symmetrically in front and behind. Each winding drum 430 is wound with a suspension rope 450. The rotating shaft 420 is used to drive the winding drums 430 to rotate so as to realize the winding and unwinding of the suspension ropes 450. The bottom ends of the two suspension ropes 450 are connected to a mounting plate 500. The mounting plate 500 is used to fix the LED light 600 and transmit the lifting power. The LED light 600 is installed at the bottom of the mounting plate 500 by bolts.

[0021] In this embodiment, two clearance holes 301 are provided on the top of the top plate 300, and two suspension ropes 450 pass through the two clearance holes 301 respectively. The top and bottom of the inner wall of the clearance hole 301 are rounded, which reduces the wear of the suspension ropes 450.

[0022] Specifically, the top of the mounting plate 500 is provided with two lifting rings 510 arranged symmetrically front to back. The two lifting rings 510 are respectively connected to two lifting ropes 450. The lifting rings 510 are used to connect the lifting ropes 450 and the mounting plate 500.

[0023] Furthermore, a limiting plate 520 is provided on the rear side of the mounting plate 500. A rectangular hole 521 is provided at the bottom of the limiting plate 520 and near the rear side. The limiting plate 520 restricts the horizontal displacement of the mounting plate 500 to ensure vertical lifting.

[0024] Furthermore, a rectangular upright 700 is provided between the base 100 and the top plate 300 and near the rear side. The rectangular upright 700 passes through the rectangular hole 521. The inner wall of the rectangular hole 521 does not contact the outer side of the rectangular upright 700. The rectangular upright 700 serves as a vertical guide rail for the lifting and lowering of the mounting plate 500.

[0025] Furthermore, each of the four inner walls of the rectangular hole 521 is provided with a groove 522, and each of the four grooves 522 is rotatably connected with a roller 523. The four rollers 523 roll on the four sides of the rectangular upright 700 respectively, and the rollers 523 reduce the frictional resistance between the rectangular upright 700 and the limiting plate 520.

[0026] Furthermore, a controller for controlling the forward and reverse rotation of the motor 440 is provided on the lower middle part of the front side of the fixed vertical plate 200. The controller controls the height of the LED light 600 and operates with an external power supply.

[0027] Furthermore, mounting holes are provided on the top of the base 100 and near the four corners. The base 100 is installed on the ground with anchor bolts to enhance stability.

[0028] In this embodiment, the adjustable-height LED light is used by the user to start the motor 440 via the controller on the front of the fixed vertical plate 200. The motor 440 drives the rotating shaft 420 to rotate forward or backward, which drives the winding drum 430 to simultaneously wind up or release the suspension rope 450. The suspension rope 450 is connected downward to the lifting ring 510 of the mounting plate 500 through the clearance hole 301. The height of the mounting plate 500 is adjusted by winding and releasing the suspension rope 450. During the lifting and lowering of the mounting plate 500, the rectangular hole 521 of the limiting plate 520 moves vertically along the rectangular upright 700, and the roller 523 in the groove 522 rolls against the side of the rectangular upright 700 to reduce friction. When the LED light 600 reaches the target height, the controller stops the motor 440, and the electromagnetic brake automatically locks the motor 440 shaft to fix the position of the suspension rope 450. The user can adjust the height of the LED light 600 at any time according to the needs of the user via the controller. When the power is off, the electromagnetic brake maintains the tension of the suspension rope 450 to prevent the LED light 600 from accidentally sliding down.
